SPECIFICATION forming part of Letters Patent No. 447,068, dated February 24, 1891.

Application filed October 24, 1890. Serial No. 369,267. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM E. DIXON, of the city of Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is a front elevation of a portion of the upper and lower sashes of a window locked together by my improved. device. Fig. 2 is a vertical section at line 2 2 of Fig. 1, looking to the right. Fig. 3 is a horizontal section on line 3 3 of Fig. 1. Fig. 4 is an enlarged detail, being a longitudinal section of a portion of the apertured plate that is to be secured to the upper sash.

This invention relates to window-sash fasteners, and has for its object to provide a device by which either or both of the sashes of a window can be held and securely locked in any desired position, and I accomplish this object by providing the upper sash of a window with an apertured plate, by providing another apertured plate to be fixed to the window-casing, and by rigidly securing to the upper edge of the lo wersash an eye or staple located between the two apertured plates and a locking-bolt adapted to pass through the apertured plate on the casing, the. eye or staple, and the apertured plate on the upper sash, such locking-bolt being provided at its end with a side lug or projection, which engages with the last-named apertured plate and thereby holds the sashes locked in position, all as illustrated in the drawings, and as hereinafter described.

That which I claim as new will be pointed out in the claim.

In the drawings, A represents the upper sash of a window, and B the lower sash of a window.

0 represents an ordinary window-casing.

D is a plate secured in any suitable manner to the side of the casing O, the plate extending some distance above the upper rail of the lower sash when such lower sash is down. This plate D, as shown, is provided with a number of holes a, through which the locking-bolt can be passed.

E is a long narrow plate secured in any suitable manner to one of the side rails of the upper sash. b are holes in the plate E, formed so as to receive the end of the locking-bolt.

F is an eye or staple rigidly secured in any suitable manner to the upper edge of the lower sash and between the two plates D and E. As shown, the eye F is secured to a small plate a, which is screwed to the lower sash, as shown in Fig. 3; butit is evident that such eye may be attached in other ways.

G is a locking-bolt, on the end of which is formed a side lug or projection d, as shown in Fig. v

e is a thumb-piece formed on the outerend ot' the locking-bolt.

f is a chain, by which the locking-bolt is secured to the window-casing.

g are notches to permit the lug d to pass through a hole I) in the plate E, a notch being 7 provided for each of such holes.

h are annular grooves in the back of the plate E, one around each hole I) to receive the projection or lug (Z of the locking-bolt.

The plate E is of the same construction as the corresponding plate of Patent No. 440,142, dated November 11, 1890, granted to me.'

hen the parts D, E, and F have been secured in place, as shown in the drawings, and it is desired to lock the two sashes together, the bolt G is to be inserted through one of the holes a of the plate D and through the eye F, and its end inserted into one of the holes I) in the plate E. When this has been done, the locking-bolt is to be turned on its axis by the aid or the thumb-piece e, the lug or projection (Z turning in the annular groove h around the hole into which the bolt has been inserted. The sashesare thuslocked. When the position of the upper sash only is to be changed, the bolt G is to be withdrawn front the hole b, in which it has been placed, (but it need not be withdrawn but a short, distance,) and when the sash has been adjusted to the desired position the bolt is to be pushed into the hole I) that is brought opposite to the bolt, and the bolt again turned, as before described. When, however, the position of both sashes is to be changed or the lower sash only is to be-moved, the bolt is to be drawn out of the hole 6, into which it has been placed, and also out of the eye F and thehole a, through which it has been inserted. The sashes are then to be adjusted as required, but so as to bring into line one of the holes a, the eye F, and one of the holes b, through which the bolt G is then to be inserted and turned to lock it, as before described.

The plates E D can be made of such length as to permit the sashes to be adjusted and locked by the bolt Gin any-desired position.

As shown in Figs. 1 and 3, the holes a in the plateD are not directly oppositethe holes Z) in the plate E, the object of this construction being to make the plate D as light weight as possible, which of course is desirable. When constructed as shown, however, itis to be understood that the holes a are to be a little larger than necessary to permit the bolt G to pass through them, so that the bolt can beturned to pass through the eye F and into one of the holes I), or else such holes a should be made of the right size to admit the bolt G, but slightly inclined.

\Vhen it is not desired to have the sashes locked at all, the bolt can readily be withdrawn and allowed to depend from the chain f.

The device as a whole can be very readily 447,ces

and cheaply made and the parts D, E, and F can be quickly and firmly secured in place on any window and without defacing the sashes or casing any more than is done by in- 0 serting a few screws therein, and when applied the device will be found to be a very strong one, and one that can be readily operated from the inside, but impossible to work from the outside without breaking the window-glass or injuring the window-sashes.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is as follows:

In a sash-fastener, the eye F, secured rigidly to the lower sash of a window, in con1- bination with the locking-bolt G, having a lug or projection cl on its inner end,an apertured plate E, secured to one side rail of the upper sash to recei e and hold the end of the bolt G and its lug or projection cl, and the apertured plate D, secured to the window-casing, substantially as and for the purpose specified.
